- Executive summary:
The vapour pressure of the test material was investigated in a study conducted via methodology similar to that outlined in the standardised guideline OECD 104 using the gas saturation method.
In this method vapour pressure is calculated by measuring vapour concentration (amount of evaporation/volume of gas) while carrier gas (mainly nitrogen) flows in contact with the sample of certain temperature generating saturated vapour of the sample. The determination is done based on the assumption that vapour obeys the ideal gas law.
The evaporation rate of sample is obtained by means of measurement of weight decrease rate of sample by electronic balance and carrier gas flow rate is measured by flow meter to obtain vapour concentration of the sample. The determination was carried out at room temperature and 49 °C
Under the conditions of this study, the vapour pressure of the test material was determined to be 0.0923 Pa at room temperature (22 to 24 °C) and 1.36 Pa at 49 °C.

Additional information
The vapour pressure of the test material was investigated in a study conducted via methodology similar to that outlined in the standardised guideline OECD 104 using the gas saturation method. The study was assigned a reliability score of 2 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
In this method vapour pressure is calculated by measuring vapour concentration (amount of evaporation/volume of gas) while carrier gas (mainly nitrogen) flows in contact with the sample of certain temperature generating saturated vapour of the sample. The determination is done based on the assumption that vapour obeys the ideal gas law.
The evaporation rate of sample is obtained by means of measurement of weight decrease rate of sample by electronic balance and carrier gas flow rate is measured by flow meter to obtain vapour concentration of the sample. The determination was carried out at room temperature and 49 °C
Under the conditions of this study, the vapour pressure of the test material was determined to be 0.0923 Pa at room temperature (22 to 24 °C) and 1.36 Pa at 49 °C.
